How to Convert SWF to AVI for LedEdit — Free Methods (2026)

SWF (Flash) effects are common in the LED community, but LedEdit 2014 works best with AVI files. If you want to skip conversion entirely, our guide on importing SWF effects directly into LedEdit covers the native import process. SWF effects often have lower quality, smaller dimensions, and compatibility issues. Converting to AVI gives you better quality, native LedEdit import, and smoother playback on your T-1000S.

Why Convert SWF to AVI?

AVI is the best format for LedEdit 2014 because:

• LedEdit imports AVI natively (no conversion needed)
• AVI is uncompressed — no quality loss
• AVI renders exactly as intended on your LED matrix
• The T-1000S plays AVI files smoothly at 30 FPS

Method 1: Screen Recording (Recommended)

The most reliable method. Records the SWF animation playing in real-time.

Using Screen2Gif (Free)

1. Download Screen2Gif from screen2gif.com
2. Open your SWF file in a Flash player (Ruffle or old Flash Player)
3. Launch Screen2Gif and set the recording area to match the animation window
4. Set recording frame rate to 30 FPS
5. Play the SWF animation
6. Click Record in Screen2Gif
7. When the animation finishes, click Stop
8. Go to File → Save As → select AVI format
9. Set quality to maximum
10. Save the file

Tips for best quality:

• Record at the exact resolution of the SWF animation (e.g., 64x64, 128x128)
• Set your screen scaling to 100% (no zoom) to avoid blurry captures
• Use a dark background to avoid capturing desktop elements
• Record a few seconds of the animation, then trim to the loop point

Using OBS Studio (Free)

1. Download OBS Studio from obsproject.com
2. Add a Window Capture source and select the Flash player window
3. Set output settings: Settings → Output → Recording → AVI format
4. Set recording format to AVI
5. Set encoder to raw (no compression) for maximum quality
6. Play the SWF animation
7. Click Start Recording
8. Click Stop Recording when done

Method 2: FFmpeg Conversion (Command Line)

If you have the SWF file and want to convert it directly:

# Basic conversion
ffmpeg -i input.swf -pix_fmt rgb24 output.avi

# With specific resolution (e.g., 64x64 for LED matrix)
ffmpeg -i input.swf -vf scale=64:64 -pix_fmt rgb24 output.avi

# With 30 FPS and loop
ffmpeg -stream_loop -1 -i input.swf -r 30 -pix_fmt rgb24 output.avi

FFmpeg flags explained:

• -i input.swf — Input file
• -vf scale=64:64 — Resize to 64x64 pixels (match your LED matrix)
• -pix_fmt rgb24 — Use RGB color format (best for LED strips)
• -r 30 — Set frame rate to 30 FPS
• -stream_loop -1 — Loop the animation indefinitely

Install FFmpeg:

Windows: Download from ffmpeg.org and add to PATH. Mac: brew install ffmpeg Linux: sudo apt install ffmpeg

Method 3: Online Converters

Free online tools for quick conversion:

• CloudConvert (cloudconvert.com) — Supports SWF to AVI, adjustable quality
• Zamzar (zamzar.com) — Simple upload and convert
• Convertio (convertio.co) — Supports batch conversion

Limitations of online converters:

• File size limits (usually 100MB max)
• No control over frame rate or resolution
• Quality may be reduced by compression
• Requires internet connection

Method 4: Adobe Animate / Flash Professional

If you have access to Adobe Animate (formerly Flash Professional):

1. Open the SWF file in Adobe Animate
2. Go to File → Export → Export Video
3. Set format to AVI
4. Set resolution to match your LED matrix
5. Set frame rate to 30 FPS
6. Click Export

This gives the highest quality conversion but requires a paid Adobe subscription.

Recommended Settings for LED Matrix

When converting SWF to AVI for LED use, match these settings to your hardware:

Important: Match the AVI resolution to your LED matrix exactly. If your matrix is 64x64, the AVI should be 64x64 pixels. Scaling in LedEdit reduces quality. For a deeper look at how AVI compares to MP4 for LED software, see our MP4 vs AVI guide.

Importing Converted AVI into LedEdit

1. Open LedEdit 2014
2. Create a new project with your T-1000S settings
3. Go to File → Import Effect
4. Navigate to your converted AVI files
5. Select one or multiple files
6. The effects appear in your LedEdit library
7. Double-click to preview
8. Arrange in playback order
9. Export to SD card

Batch Conversion with FFmpeg

Convert multiple SWF files at once:

Windows batch script:

@echo off
for %%f in (*.swf) do (
    ffmpeg -i "%%f" -pix_fmt rgb24 "%%~nf.avi"
)
echo Done!
pause

Linux/Mac bash script:

#!/bin/bash
for f in *.swf; do
    ffmpeg -i "$f" -pix_fmt rgb24 "${f%.swf}.avi"
done
echo "Done!"

Place the script in the same folder as your SWF files and run it. All SWF files will be converted to AVI in one batch.

Quality Tips

1. Record at native resolution — Don’t upscale or downscale during recording
2. Use 30 FPS — Matches the T-1000S playback rate for smooth animation
3. Trim to loop point — Cut the AVI to exactly 5 seconds for seamless looping
4. Remove duplicate frames — Some SWF animations have duplicate frames that waste SD card space
5. Test on a small strip first — Preview converted effects before loading the full SD card

Conclusion

Converting SWF to AVI is straightforward with free tools like Screen2Gif or FFmpeg. The AVI format gives you native LedEdit import, uncompressed quality, and smooth playback on the T-1000S. If you want to explore more free tools beyond LedEdit, our free LED animation software guide covers additional options. For the best results, match the AVI resolution to your LED matrix and use 30 FPS.
